I would use gparted.

Changes the partition table and filesystems all at the same time for you.

If you enable partition support on loop mount, then you can do this:

modprobe -r loop (Unload loop module)
modprobe loop max_part=16 (Load loop module with partition support)
losetup /dev/loop0 diskimagefile (connect loop0 to image file, which should then show /dev/loop0p1, etc as partitions on that disk image)
gparted /dev/loop0 (Use gparted to change things)
losetup -d /dev/loop0 (disconnect from loop0)
